Recently something has gone wrong with our website so that whenever you try to access an aspx file, it shows the following error:

Server Error in '/RALSWeb' Application.

Configuration Error

Unable to cast object of type 'System.Data.Linq.DataQuery`1[Username]' to type
'Username'.

I've been searching but can't find a solution. This particular table has 4 columns. The first column is the int indentifier. Column 2 is "username" (varchar50) and is the primary key. Column3 is "userID" (uniqueidentifier) and column 4 is "active" (varchar5) .

I have a webdatagrid control that is loaded by using an sqldatasource. I have add and edit methods that behave correctly, however, I have a problem when I delete a row. I can delete the row correctly from the datagrid and the database, but as soon as I select another row in the grid straight after, I get an error:

Microsoft JScript runtime error: 'undefined' is null or not an object

There are no events wired up to the row select, so it doesn't appear to be that.

I created a Workflow with Nintex Workflow 2007 (on SharePoint 2007) to send/receive data to BizTalk 2009. It worked fine already. But now I get the following error mesage in the EventViewer:

Nintex Workflow; Build: 11000 (http://ls457/_layouts/nintexworkflow/BiztalkHandler.ashx)
No workflows are waiting for a BizTalk message with message Id of 'GeneralAccessRequest_2010-08-23T15_00_04_44961212B370C554EDFAC41C1201ED6CEFB' on teamsite http://ls457/sites/testapp. No processing has been done.

What could that mean? Any ideas? I definitely changed nothing on the orchestration or BizTalk administration. The BizTalk action sends the data correctly to it's destination (database), but it seems that nintex doesn't receive any return data. I don't think
it's a BizTalk problem, because in the BizTalk Message Tracking Database the Message is listet, so it has been sent correctly by BizTalk. But the handler probably has problems to find/receive this message.

I'm getting a really strange error in my application when under heavy load. The page(s) pull information from our SQL database and when this error occurs, I don't get a real error message. Instead, the error information looks like the following:

I upgraded my web application from visual studio 2003 to 2008. When I want to create a report in visual studio 2008 and receiving this error at runtime. I am able to compile but when runnning thats when I am getting this error.

How can I solve this problem? please help.

I am developing a SSIS package to add data from an XML file to an existing SQL Server table. I have completed several similar projects, but on this XML file I am getting the error from the Data Flow tab between the XML Task and Data Flow Task:
Error: 0xC002F304 at XML Task, XML Task: An error occurred with the following error message:
"'', hexadecimal value 0x15, is an invalid character. Line 28, position 54.".
Error: 0xC002928F at XML Task, XML Task: Property "New Source" has no source Xml text;
Xml Text is either invalid, null or empty string.

Warning: 0x80019002 at zSTU_TS_Element: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (2) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "zStu_TS_Element.dtsx" finished: Failure.
Do you know how I can fix this?
This is the line it is referring to:

Hello,
I am using "last_run_outcome" value = 0 (fail) or 1 (pass) from sysjobsteps to identify if the job has failed.
So if the job has failed, can I get the Error Message from SQL ? (which we can see in Job History).
Thanks,
Prabhat
